14 DCN Next Generation Installation and User Instructions System Design and Planning en 14 1 DCN design 1.1 Introduction The DCN Next Generation has two parts: the DCN and the optical network. This chapter tells how to design the DCN. 1.2 Calculation tool The calculation tool makes the planning and design of the DCN easier. You can find the calculation tool on the CD-ROM that is supplied with your system. 1.3 Concepts Introduction This section gives necessary data to understand the limitations in section Trunk and tap-off sockets The DCN uses two types of socket: DCN trunk sockets Use the DCN trunk sockets to make a loop-through in the trunk of the DCN. DCN tap-off sockets Use the DCN tap-off sockets to make more branches in the DCN. A DCN tap-off socket always regenerates the digital DCN signal Cables Many devices used in the DCN have a 2 m cable. If necessary the extension cable (LBB4116) can extend the device cables. 1.4 Limits Make sure these limits are not exceeded when you design the DCN: Limit 1: Control capacity The maximum number of active devices in a DCN that a central control unit can control is 245. For the maximum number of active devices that a multi CCU can control, refer to section The number of passive devices is without limit (refer to section 1.5). Limit 2: Power capacity The maximum power that one DCN socket of the central control unit can supply is 65 W. The total power that the DCN sockets of the central control unit can supply is 130 W. The maximum power that one DCN socket of the extension power supply can supply is 85 W The total power that the DCN sockets of the extension power supply can supply is 255 W. Refer to section 1.6. Limit 3: Loop-throughs The maximum number of loop-throughs in succession is 50. If there are more than 50 loop-throughs, the signal must be regenerated with a trunk splitter (LBB4114/00). Limit 4: Tap-off connections The maximum number of tap-off connections in succession between the central control unit and the last tap-off in a branch is four. If there are more than four tap-off connections in succession, the system does not operate correctly. Limit 5: Cable lengths Refer to section 1.7: With regenerative tap-offs, the maximum cable length is 250 m from the central control unit to the furthest device in any branch of the DCN. The maximum cable length from the central control unit to the first regenerative tap-off is 100 m. The maximum length of the cable between regenerative tap-offs is 100 m. Open-ended cables can cause an incorrect operation of the system. The total cable length includes the 2 m long device cables.

15 DCN Next Generation Installation and User Instructions System Design and Planning en Control capacity Active devices Active devices are devices that can: Receive data from the central control unit. Transmit data to the central control unit. Active devices must have an address (refer to section 8.7) Passive devices Passive devices can only receive data from the central control unit Overview The following table shows the active and passive devices in the DCN. table 1.1: Active and passive devices Device Type DCN-CON Active DCN-CONCS Active DCN-CONFF Active DCN-CONCM Active DCN-DDB Passive/Active DCN-DDI Active DCN-DISL Active DCN-DISS Active DCN-DISCS Active DCN-DISD Active DCN-DISDCS Active DCN-DISV Active DCN-DISVCS Active DCN-EPS Passive DCN-FCS Passive DCN-FVU Active DCN-FVU-CN Active DCN-IDESK Active LBB4114/00 Passive LBB4115/00 Passive 1.6 Power capacity Introduction Each device uses power, and most devices do not have an independent power supply Power consumption The following table shows the power each device in the DCN uses. table 1.2: Power consumption Device Watt DCN-CON 3.4 DCN-CONCS 3.7 DCN-CONFF 4.2 DCN-CONCM 4.2 DCN-DDB 2.0 DCN-DDI 4.5 DCN-DISL 2.75 DCN-DISS 2.75 DCN-DISCS 2.9 DCN-DISD 2.8 DCN-DISDCS 3.15 DCN-DISV 3.05 DCN-DISVCS 3.20 DCN-EPS 0.8 DCN-FCS 0.9 DCN-FVU 1.0 DCN-FVU-CN 1.0 DCN-IDESK 3.6 LBB4114/ LBB4115/ The power consumption of the DCN-DDI includes the power consumption of all flush-mounted devices that you can connect to it.

17 DCN Next Generation Installation and User Instructions System Design and Planning en Overload indication Each DCN socket of the central control unit and extension power supply has a red LED that comes on to show that there is a power overload. An overload occurs when: The necessary power for the devices is greater than that is supplied. A short-circuit occurs. When an overload occurs, that socket is deactivated, and the connected devices do not operate. The socket checks every 8 seconds (DCN-CCU, DCN-CCUB) or 30 seconds (DCN-EPS) for power overloads Extension cables Extension cables (LBB4116) have a direct effect on the available power. The longer an extension cable, the less power is available to drive the connected devices. You must chose the length of the extension cables carefully (refer to section 1.7.5). 1.7 Cable lengths Maximum length The cable length between the central control unit and the furthest device from the central control unit must not be more than 250 m. The cable length includes the device cable and extension cables To first regenerative tap-off The total cable length between the central control unit and the first regenerative tap-off socket must not be more than 100 m. This includes the device cable and extension cables Between regenerative tap-offs The total cable length between two regenerative tap-off sockets must not be more than 100 m. This includes the device cables and extension cables Open-ended DCN cables Open-ended DCN cables are DCN cables of which the socket is not connected to a device in the DCN. Open-ended cables can cause the system to operate incorrectly. You can close the extension cable with a termination plug (refer to section 40). When the open-ended cable is connected to a termination plug, the system operates correctly Power correction Introduction The necessary power from a DCN socket of the central control unit and the extension power supply is affected by: The type and number of connected devices. The lengths of the connected extension cables. The power correction graph (refer to figure 1.4) corrects the power level to compensate for the extension cables Calculation To find the correction for each DCN socket of the central control unit and the extension power supply with the graph, you must first calculate: The total power consumption of the devices that are connected to the socket. Refer to section The length of the longest extension cable sequence. Refer to section

18 DCN Next Generation Installation and User Instructions System Design and Planning en Total power consumption Do as follows: 1 Find the power consumption of each device from the consumption table (refer to table 1.2). 2 Add together the power used by all the devices. The result is the total power consumption of the devices that are connected to the socket Length of the longest extension cable sequence Do as follows: 1 Add together the lengths of all extension cables in the longest sequence Graph The power correction graph (refer to figure 1.4) corrects the power level to compensate for the extension cables. Do as follows: 1 Find the total power consumption (refer to section ) on the vertical axis (Y) of the power correction graph. For example, 40 W. 2 Find the length of the longest extension cable sequence (refer to section ) on the horizontal axis (X) of the power correction graph. For example, 60 m. The intersection of both values gives the necessary power from the socket. In this example it is 53 W. For example, an extension cable of 20 m is connected directly to a DCN socket of the central control unit. To the extension cable, a trunk splitter is connected. To each tap-off socket of the trunk splitter, an extension cable is connected. One extension cable has a length of 10 m, the other extension cable has a length of 40 m. The length of the longest extension cable sequence is, in this example: = 60 m Y: Power (Watt) DCN-CCU, DCN-CCUB + DCN-EPS X: Extension cable (m) figure 1.4: Power correction graph

23 DCN Next Generation Installation and User Instructions System Design and Planning en 23 2 Optical network design 2.1 Introduction The DCN Next Generation has two parts: the DCN and the optical network. This chapter tells how to design the optical network. 2.2 Calculation tool The calculation tool makes the planning and design of the optical network easier. You can find the calculation tool on the CD-ROM that is supplied with your system. 2.3 Limits Make sure that these limits are not exceeded when you make the optical network: Limit 1: Control capacity The maximum number of nodes in the optical network is 63 (refer to section 2.4). Limit 2: Number of devices The maximum number of devices that you can connect to the optical network of the central control unit is 16. The maximum number of devices that you can connect to the network controller is determined by the control capacity. Limit 3: Power capacity The optical network sockets of the central control unit or network controller can supply the following maximum powers (also refer to section 2.5): Central control unit - total maximum power of 65 W for all sockets. Network controller - maximum power of 55 W for each socket. Limit 4: Cables Refer to section 2.6: The maximum length of a POF cable is 50 m. The maximum cable length (POF and GOF) of the optical network is dependent on the number of nodes in the optical network. The minimum bend radius of a 90 degree bend in a POF cable is 25 mm. The minimum coiling radius of a POF cable is 100 mm. 2.4 Control capacity Each device in the optical network has a number of nodes (refer to table 2.1). The maximum number of nodes in the optical network is 63. table 2.1: Nodes Device Nodes DCN-CCU 2 LBB4402/00 1 LBB4404/00 1 LBB4410/00 1 LBB4414/10 0 INT-TX04 1 INT-TX08 2 INT-TX16 4 INT-TX32 8 PRS-4DEX4 1 DCN-NCO Power capacity Introduction It is important that the devices in the optical network do not use more total power than you supply to the devices.

If more power is necessary, you must install external power supplies in the optical network. (refer to ). The devices below can connect to external power supplies: LBB4410/00 Network Splitter (refer to chapter 41). LBB4414/10 Fiber Interface (refer to chapter 42) DCN-CCU The central control unit supplies power to: the optical network the DCN sockets. For an overview of the maximum power that the central control unit can supply refer to figure 2.1. DCN-CCU DCN-NCO If a network controller is connected, it will supply power to the optical network. In this case, the DCN-CCUs then only supply power to the DCN sockets. If a glass optical fibre is used to connect a remote CCU, this CCU then supplies the power for that part of the optical network. The maximum power that each of the optical network sockets of the network controller can supply is 55 W Overload indication Each optical network socket of the central control unit has a red LED that comes on to show that there is a power overload. An overload occurs when the necessary power for the devices is greater than that supplied. The sockets are set to off and the devices connected to the central control unit do not operate. The socket checks every 8 seconds. The network controller does not have an overload indication P<65W If only one of the optical network sockets has a power overload, the two overload LEDs come on, and the power will be removed from both sockets. DCN-CCU 2.6 Cabling DCN-CCU P<65W Introduction Many devices in the optical network have two optical network sockets that are interchangeable. You can use the two optical network sockets to make a redundant ring. The optical network uses two types of cable: Plastic Optical Fiber (POF). Glass Optical Fiber (GOF) P<130W The two optical network connectors are the same. figure 2.1: Optical network power supply: DCN-CCU

25 DCN Next Generation Installation and User Instructions System Design and Planning en Optical fiber length Because of optical attenuation, the maximum length of optical network cables (LBB4416) is 50 m. You can use GOF and fiber interfaces to increase the distance between devices to more than 50 m and less than 1500 m (refer to chapter 42). If the distance between two devices is less than 100 m, use a network splitter between devices to remove the use of fiber interfaces. Use only the trunk sockets of the network splitter in this case Cable couplers You can use the LBB4419/00 Cable Couplers to connect optical network cables to each other. A cable coupler causes optical attenuation. Each cable coupler decreases the maximum distance between two devices in the optical network (normally 50 meters) with 20 meters Maximum cable length The maximum cable length (LBB4416 and GOF) of the optical network is dependent on: The number of nodes The number of LBB4414/10 Fiber Interfaces Do as follows: 1 Find the number of nodes of each device from the node value table (refer to table 2.1). Add together the nodes of all devices. 2 With the value of step 1, use the graph (refer to figure 2.2) to find the maximum cable length without LBB4414/10 Fiber Interfaces. 3 Count the number of LBB4414/10 Fiber Interfaces. Each fiber interface decreases the maximum cable length from step 2 with 18 m. Max. cable length (m) Nodes figure 2.2: Cable correction graph

26 DCN Next Generation Installation and User Instructions System Design and Planning en Bending The minimum bend radius of a 90 degree bend in an LBB4416 cable is 110 mm (refer to figure 2.3). A 180 degree bend is the same as two 90 degree bends. R=110 mm 2.7 Example layouts Introduction The number and type of devices that make the optical network give the layout of the optical network. This chapter shows examples of the possible layouts of optical networks Basic optical network Refer to figure 2.5 for an example of a basic optical network. DCN-CCU figure 2.3: Bend radius Coiling The minimum coiling radius of an LBB4416 cable is 110 mm (refer to figure 2.4). LBB4404/00 LBB4402/00 R=110 mm PRS-4DEX4 INT-TX figure 2.5: Basic optical network figure 2.4: Coiling radius

27 DCN Next Generation Installation and User Instructions System Design and Planning en Redundant optical network The basic optical network (refer to figure 2.5) has no redundant cables. If the cable between the central control unit (DCN-CCU) and the audio expander (LBB4402/00) breaks, the central control unit cannot transmit data to the audio expander. A solution for this problem is to use a redundant cable (refer to figure 2.6) Tap-offs The network splitter (LBB4410/00) lets you make tap-offs (refer to figure 2.7). Tap-offs cannot be redundant. If the cable between the network splitter and the digital audio expander (PRS-4DEX4), becomes defective, the digital audio expander has no connection to the central control unit.

The operational mode is the default mode for the interpreter desk. If the desk is not configured, the display shows the screen: You cannot put a desk that is not configured in the operational mode Auto-relay interpretation Where the interpreter does not know the source floor language, the system has an automatic relay function (refer to figure 33.12). One interpreter makes an interpretation from the source language (floor signal) in a language that the other interpreters know. This language is the auto-relay interpretation. The auto-relay interpretation automatically replaces the floor signal on all interpreter desks. All interpreters use the auto-relay interpretation to make interpretations. The example in figure shows that the floor signal is Chinese. The auto-relay is enabled at the Chinese interpreter desk. The Chinese-to-English interpreter selects output B and sends an English auto-relay interpretation to all other interpreter desks. The LED adjacent to the Floor/Auto-relay button shows on all other interpreter desks that the interpreter desk receive an auto-relay interpretation Normal interpretation In the usual procedure for interpreters (refer to figure 33.11), the interpreter knows the source floor language. The interpreter makes an interpretation of the source language in the target language. The language distribution channels transmit the target language to the delegate units.

258 DCN Next Generation Installation and User Instructions Peripheral Devices en Mode Introduction Set the mode of the data distribution board with the S8-3 switch. The data distribution board can be: A passive unit that receives data from the central control unit (passive mode). An active unit that also transmits data to the central control unit (active mode) Passive mode You must put the data distribution board in the passive mode when: You use data distribution board to send data to a hall display. You use data distribution board for speak slowly or help signaling. You only use the parallel outputs of the data distribution board. If the data distribution board is in the passive mode, you must give it an address (refer to section ). This address defines the application of the data distribution board. When you start the system for the first time, you must push the de-init switch of the data distribution board to send its address to the central control unit (refer to section 8.7). When you use the central control unit to erase the addresses of all units (refer to section 8.7), you must not push the de-init switch again. The central control unit remembers the addresses of the passive data distribution boards when it is started again Active mode You must put the data distribution board in the active mode when you use the parallel inputs of the data distribution board. The maximum number of data distribution boards in the system is 15. If the data distribution board is in active mode, the central control unit gives it an address. The system ignores the passive mode address of the data distribution board in the active mode (refer to section ). When you start the system for the first time, you must push the de-init switch of the data distribution board to obtain an address. When you use the central control unit to erase the addresses of all units (refer to section 8.7), you must push the de-init switch again to obtain a new address. The central control unit does not remember the addresses of the active data distribution boards when it is started again Addresses If necessary, set the address of the data distribution board with the S8-6, S8-7 and S8-8 switches. This address is only used when the data distribution board is in the passive mode (refer to section ). The address defines the application of the data distribution board (refer to table 47.4). table 47.4: Addresses Address S8-6 S8-7 S8-8 Description Numeric display (refer to section ) Alpha-numeric display 1 (refer to section ) Alpha-numeric display 2 (refer to section ) Status display (e.g. synoptic display, refer to section ) Reserved Speak slowly signaling (refer to section ) Help signaling (interpreter booth 1 to 16, refer to section ) Help signaling (interpreter booth 17 to 31, refer to section ).
